My mother calls me today crying and tells me that my father killed my Polish rooster today. I live within city limits and my parents have 5 acres, so my chickens live there. I'm about 1 1/2 miles away. "Sideshow Bob" was a year old. They've told me that he tries to flog them, but I never had a problem with him. He lived in my house for 6 weeks and was very tame when he was young. I've seen my dad "playing" with him- he would flog my dad and my dad would lift him up with his foot and throw him back. The rooster would keep coming back at him. My dad had thought this was "funny". I guess it must have went too far today. My mom is upset at my dad's behavior, saying he's going crazy. (He's 67) I am wondering how long my hens will lay fertile eggs. The hens only started laying about 7 weeks ago. They are aso a year old. (Polish) I hatched 4 chicks 3 weeks ago and have eggs I am hatchig for someone else that are due to hatch next week. I promised my sister's friend I would incubate some duck eggs when these chicks hatch. I can't hatch my chicken eggs with the duck eggs can I? The humidty levels are different, right?
